If you read these lines, it certainly means that just like me, you have already spoiled a lot of time online, searching for some relevant information about red and rose gold alloys. And if you actually have, you probably noticed the lack of feature articles on the subject. An incredible lack when compared to the huge offer of red and rose gold jewels featured on websites, which introduce them brazenly as a genuine novelty. But let’s be clear here. These alloys are nothing but old (however valuable) recipes, which have become the new darlings of the luxury marketers who found there a new winning formula to make something new out of the old … Since the blog of LA Joaillerie highlights the red colour this month, I ‘d like to share with you a new article compiling  the major characteristics of red gold and of its “baby pink” variation (see point # 6), just to debunk a few misconceptions and help you to understand the reasons behind this trend.   In this article: IN A HURRY?
